GARDEN-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 735,038, dated July 28, 19034 Application led November 22, 1902. Serial No. 132,361. (No model' T all whom, it 1v1/ty concern.-

Beitknown thatLDELMER H.MooRE,a citizen of the United States, residingrat Greenville, in the county of Montcalm, State of Michigan, haveinvented certain new and usefullmprovements in Garden-Cultivators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which 1o it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part ot' this specification. i5 This invention relates to a garden-cultivator; andit consists inthe construction and arrangement of partshereinafter fully set forth, and pointed out particularly in the claims.

The objects of the invention are to provide 2o simple and eflcient means for cultivating on both sides of a row of plants, for adjusting the cultivator to obtain any desired width be-A tween the transporting-wheels and rigidly connecting the adjustable parts, and to provide a double set of cultivating-tools, either set of which may be brought into use by simply reversing the implement.

A further object is to provide specific features of construction whereby simplicity and 5o eheapness are attained.

The above objects are accomplished by the construction illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my improved cultivator, the handles being broken away. Fig. 2 is aside elevation of the cultivator. Fig. f3 is also a side elevation, but showing the cultivator reversed, so as to bring into operation a different set of tools from those in opera- 4o tion in Fig. 2. Fig. 4 is a transverse section on line et e of Fig. 1. Fig. 5 is an enlarged fragmentary view in section through a portion of one of the handles, showing the L- shaped clamping-bolt adapted to secure one of the transversely-adjustable bars which unite the handles in a manner to permit of their lateral movement. Fig. 6 is` an enlarged transverse section on line 6 of Fig. 1.

Referring to the characters of reference, 1

5o designates the handles, whose outer ends diverge sufficiently to allow the operator to thumb-nut 11.

walk between them. The transporting-wheels 2 are journaled upon axle-bolts 3, which pass through the hubs 2a of said wheels and through the interposed nuts 2b and the forward ends of the handles, the inner ends of said bolts screwing into theV brackets 4, which project inwardly from the handles, as shown in Fig. 1, aording a very simple and inexpensive means for journaling the wheels upon the handles and maintaining them in position.

The axle-bolts of the transporting-Wheels being independent, said wheels are therefore allowed to move laterally toward and from each other. To connect the transporting-wheels in a manner to'permit of .their adjustment, the crossed levers 5 are employed, which are pivoted together at their point of crossing, as at 6, and at their forward ends are pivoted at 7 to the brackets 4. The rear ends ot' the levers 5 are provided with longitudinal slots 8 and are bent upwardly .and downwardly, respectively, to cause them to stand apart. Lying upon the upper face of the handles and crossing between them is a transverse bar 9, one end of which is pivoted on the npper end of the L-bolt 10, which receives the Passing through the bar 9 is a pin 12, which lies in the slot 8 of the upper lever 5, whereby said lever becomes attached to said bar. Mounted upon the under face of thel handles is a transverse bar 13, which is pivoted to one of the handles upon the L-holt 14, which passes therethrough and receives the thumb-nut 15. The angle portion of the bolt 14 forms a loop which embraces the bar 9 in a manner to allow said bar to slide therethrough when the nut 15 is loosened, but which affords means for securely clamping the bar 9 upon the tightening of said nut. In like manner the angle portion of the'bolt 10 embraces the lower bar 13, whereby said bars may be allowed to slide through the loops of said bolts, respectively, when the thumb-nuts of the bolts are loosened, but are securely clamped to said bolts by the tightening of said nuts, forming of said barsa bridge or truss between the handles, which rigidly unites them after they have been properly adjusted. Passing through the bar 13 is a pin 16, which engages in aslot 8 of the lower lever 5, thereby establishing a slidable conlOO nection between said lever and bar 9, as bel Having thus fully set forth my invention,

tween the bar 9 and the upper lever 5. By this arrangement it will be seen that upon loosening the thumb-nuts 11 and 15 the handles 1 may be separated, lthereby actuating the levers 5 to separate the transporting wheels, allowing said wheels to be adjusted, as desired, to pass upon each side of a row of plants. When properly adjusted, the parts are securely clamped in place by tightening said nuts. Should it be desired to reduce the distan ce between the transporting-wheels, the handles may be brought together after the nuts 11 and l5 have been loosened, thereby operating the crossed levers 5 to move the transporting-wheels closer together, as will be well understood. The slots 8 in the crossed levers in these operations allow of a movementofthe connecting-pins 12 and 16 therein, as the bars 9 and 13 are adjusted transversely.

Mounted upon the axle-bolts upon each side of the hubs of the transportingwheels are the radial arms 17 and 18. Attached to the outer ends of these arms are the opposed circle-bars 19 and 20. interposed between the opposite ends of said circle-bars are' the sleeves 2l, through which pass the tie-bolts 22, whereby said bars are coupled together. The inner bars 20 pass the face of the handles 1 and are adjustably secured thereto by the L-shaped clamping-bolts 23, which pass through the handles and receive on their outer ends the thumb-n nts 24. Upon the opposite ends of the circle-bars are attached the plows 25 and the cultivating-shovels 26, the outer circle-bars 19 at one end being bent rearwardly, as shown at 27, so as to arrange theshovels tandem. Byloosening the nuts 24 the circle-bars may be swung upon the axles of the transporting-wheels to enable the handles to be raised or lowered to suit the height of the operator. By this arrangement an iniplement is provided which enables the use of two sets ot' tools by simply reversing the handles, as illustrated in Figs. 2 and 3, bringing into use the shovels 26 or the plows 25, as desired. It will also be understood that the tools shown maybe replaced by othersiof different character, so as to adapt the implement forany desired use. The lateral adjustment of the transporting-wheels also adjusts laterally the working tools carried by the implement, so that when the wheels are adjusted to increase or decrease the distance between them the tools are in like manner adjusted.

The comparatively simple construction and ready adjustment of the implement herein shown renders it highly efcient as a gardencultivator.

what I claim as new, and desire to secure by Letters Patent, is-

1. In a garden-cultivator, the combination of the opposed laterally-movable handles, the transporting-wheels jonrnaled to said handles respectively, transverse connecting-bars, said bars being pivoted at their opposite ends to said handles, and having a slidable engagement with the handle opposite to that t0 which they are pivoted, crossed levers pivoted at their point of crossing, the forward ends of said levers being pivoted to the axlebolts of the transporting-wheels, the rear ends of said levers having slidable connection with the transverse bars extending between the movable handles.

2. In a garden-cultivator, the combination of the laterally-movable handles, adjustable connections between said handles, transporting-wheels journaled to the forward ends of said handles, and laterally movable therewith, means connecting the journals of each of said wheels with the handle opposite thereto whereby a movement imparted to the handles is imparted to the axis of the wheels, circle-bars adjust-ably mounted upon each of said handles, cultivating-tools attached to said circle-bars, and means for clamping said circle-bars to the handles.

3. Ina garden-cultivator, the combination of the laterally-movable handles, the transporting-wheels, said handles attached to the axle-bolts of said wheels, brackets projecting inwardly from said axle-bolts, crossed levers 95 having their forward ends pivoted to said brackets, said levers being pivoted together at their point of crossing and having slots in their rear ends, transverse bars carrying pins which engagein the slots of saidlevers,ineans ioo for clamping said bars to said handles to lock them against movement, adjustable circlebars mounted on the axle of the wheels carrying cultivating-tools, and means for locking said circle-bars.

4. In a cultivator, the combination of the laterally-movable handles, the transportingwheels, axle-bolts passing through the hubs of said wheels, the inner ends of said bolts passing through the handles, brackets into no which the inner threaded ends of the axlebolts are screwed, adjusting-levers pivoted to the brackets, and means connecting said adjusting-levers with the handles.

In testimony whereof I sign this speciflcax15 tion in the presencelot two witnesses.
